Which of the following is NOT a minor award?

The Military Service Award is considered a significant commendation that recognizes an individual's service in the armed forces. This award often carries a higher prestige and is associated with the sacrifices and commitments made during military service. In contrast, the other awards mentioned, such as Employee of the Quarter, Memorandum of Commendation, and Sheriff's Commendation, typically acknowledge individual performance and contributions within the employment context, making them more aligned with minor awards.

Minor awards are usually given for specific achievements or performance milestones and serve to motivate and recognize employees' contributions within their organization. The Military Service Award stands apart due to its broader implications and the serious nature of military service, thus categorizing it outside of minor awards.
